Detailed description of the invention
Describe this utility model below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
As depicted in figs. 1 and 2, according to anticentripetal spiral casing of the present utility model, including top board 10 and sidewall 20, top board 10 and sidewall 20 are internally formed centrifugal wind chamber, air inlet 11 it is provided with on top board 10, being provided with air outlet on sidewall 20, anticentripetal spiral casing also includes the splitter plate 21 being arranged on the inner peripheral surface of sidewall 20.This utility model is by arranging splitter plate 21 on the inner peripheral surface of sidewall 20, such that it is able to large scale whirlpool to be separated broken opening, reduce whirlpool yardstick and also reduce the spin intensity of gas simultaneously, reduce the flow losses of air-flow, improve blower press and efficiency, reduce whirlpool noise, thus improve the efficiency of blower fan, reduce noise.
Specifically, splitter plate 21 is parallel with top board 10, and circumferentially extending along the inner peripheral surface of sidewall 20, on the one hand reduces whirlpool yardstick, makes the whirlpool intensity of gas be reduced, and the flow losses of air-flow are also reduced；On the other hand air-flow also can be played guiding function by splitter plate 21, make air-flow will not whirlpool, combing air-flow, improve blower press and efficiency, reduce whirlpool noise, it is achieved the improvement of fan noise.Further, along air motion direction, splitter plate 21 is gradually increased along the width of the radial direction of anticentripetal spiral casing such that it is able to more effectively separates air-flow, prevents air-flow vortex.
Preferably, as in figure 2 it is shown, splitter plate 21 includes the first demarcation strip 21a and the second demarcation strip 21b being parallel to each other, the first demarcation strip 21a is near top board 10, and the second demarcation strip 21b is near base plate.Air-flow is separated into three runners by the first demarcation strip 21a and the second demarcation strip 21b, it is possible to more effectively decompose vortex.It is highly preferred that in same axial section, the width of the first demarcation strip 21a width more than the second demarcation strip 21b.Second demarcation strip 21b is used for crushing maelstrom, first demarcation strip 21a is used for crushing the little eddy current at spiral case shroud, reducing whirlpool yardstick with this, make the whirlpool intensity of gas be reduced, the flow losses of air-flow are also reduced, three runners also also function to drainage to air-flow simultaneously, make in runner air-flow will not whirlpool, combing air-flow, improve blower press and efficiency, reduce whirlpool noise, it is achieved the improvement of fan noise.Further, it is uniformly arranged along the axial direction of anticentripetal spiral casing, the first demarcation strip 21a and the second demarcation strip 21b, namely the height of three runners is the most equal, improve broken vortex and the effect of drain.
This utility model additionally provides a kind of centrifugal blower, including aforesaid anticentripetal spiral casing, such that it is able to large scale whirlpool to be separated broken opening, reduce whirlpool yardstick and also reduce the spin intensity of gas simultaneously, reduce the flow losses of air-flow, improve blower press and efficiency, reduce whirlpool noise, thus improve the efficiency of blower fan, reduce noise.
This utility model provides a kind of air-conditioning, including aforesaid anticentripetal spiral casing, such that it is able to large scale whirlpool to be separated broken opening, reduce whirlpool yardstick and also reduce the spin intensity of gas simultaneously, reduce the flow losses of air-flow, improve blower press and efficiency, reduce whirlpool noise, thus improve the efficiency of blower fan, reduce noise.
As can be seen from the above description, this utility model the above embodiments achieve following technique effect:
